BB86 and SRM

[Ferry]

I am considering a SRM powermeter for my Giant TCR advanced SL. The bike is built with a complete Dura Ace 9170 groupset. I would like to add a powermeter and carbon crank arms. In addition, as it is a BB86 bottom bracket I would like to keep the 24 mm axle.

Will the chainline change, will I need to add spacers. Are there any other things I would need to pay attention to? Any help or info is appreciated.
